A PIN code component for react native

A PIN code component for react native

react-native-pincode

A customizable PIN Code component for react native.

Using:

  • react-native-keychain to store the pin in Keychain/Keystore
  • react-native-touch-id to authenticate users with FaceID/TouchID
  • react-move for animations
  • react-native-vector-icons to use the material icons

Installation

npm install --save @haskkor/react-native-pincode

or

yarn add @haskkor/react-native-pincode

Please note that:

If you wish to use the TouchID/FaceID authentication you will have to link the library:

react-native link react-native-touch-id

If you wish to use Keychain/Keystore to store the PIN code you will have to link the library:

react-native link react-native-keychain

Please note that you might have to link those libraries manually.

IMPORTANT:
If you decide not to use Keychain/Keystore, you will have to provide a storePin property to the PINCode component.

The library uses the Vibration from React Native.
Please note that on Android it requires the Vibrate permission as stated in the doc. (add to AndroidManifest.xml)

Usage

Basic usage requires choosing between the choose, enter and locked modes.

  • choose : requires the user to choose and to confirm a PIN code
  • enter : requires the user to enter the PIN code he previously chose
  • locked : prints a locked screen for a given time if the user failed to enter his/her PIN code too many times
import PINCode from '@haskkor/react-native-pincode'
<PINCode status={'choose'}/>

One can also use a provided promise to know if a PIN code has been set by the user.

import {hasUserSetPinCode} from '@haskkor/react-native-pincode'
await hasUserSetPinCode()
